Absolutely, which is why I wrote that he had already made that decision. To accept his heritage and to use his powers for the good of those who need it, but that Zod exposes Kal-El on a much bigger scale and finally creates the symbol that'll be known as Superman.

What I mean is that Clark would help the people, but might not want to interfer with human affairs both due to him being humble, but more because of it possibly being mistaken for dominance given his superiority with the powers and being an alien. That he just want to help on a smaller more assisting scale.
But that the "Zod"-incidence changes that and makes him a world savior, only prompted by the people in the end.
